Perhaps you should try some spelling variations:
teaching change » teaching chinese, teaching chapter, teaching china
lasten teaching » based teaching, stem teaching, content teaching
change robert » change roberto, chase robert, chang roberto
die lasten » die kosten, die ersten
robert bin » robert b, robert n, robert i
ying di » ying jin
yang » lang, wang

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "tan ((ying di) OR (yang di)) die lasten teaching change robert bin ;~".
• Adding a wildcard symbol may retrieve word variants: tan ((ying di) OR (yang di)) die lasten teaching change robert bin ;*.
